@mrocklin if you get a chance, can you confirm that the values in HighLevelGraph.depedencies should be a subset of the keys of layers?

So in the following, the lambda-<...>-x is problematic, because it's not a key in layers?

python (Pdb) pp list(self.layers) ['eq-e98e52fb2b8e27b4b5158d399330c72d', 'lambda-0f1d0bc5e7df462d7125839aed006e04', 'ones-c4a83f4b990021618d55e0fa61a351d6'] (Pdb) pp self.dependencies {'eq-e98e52fb2b8e27b4b5158d399330c72d': {'lambda-0f1d0bc5e7df462d7125839aed006e04-x', 'ones-c4a83f4b990021618d55e0fa61a351d6'}, 'lambda-0f1d0bc5e7df462d7125839aed006e04': {'ones-c4a83f4b990021618d55e0fa61a351d6'}, 'ones-c4a83f4b990021618d55e0fa61a351d6': set()}

That's coming from the name of the DataArray / the dask arary in DataArray.data.
